Bacteria and archaea of the Columbia and Willamette Rivers, 16S rRNA gene amplicon library metadata

Bacterial and archaeal communities in the Columbia and Willamette Rivers in the Portland, OR, USA, region were characterized by 16S rRNA gene amplicon sequencing as part of the Lewis & Clark College spring 2022 Microbial Ecology course. Whole-water (>0.2 µm) samples were collected from: the Willamette River; the Columbia River above the confluence with the Willamette; and the Columbia River just downstream of the confluence with the Willamette. This dataset provides additional metadata to supplement the DNA sequences archived with the NCBI SRA at https://www.ncbi.nlm.nih.gov/sra/PRJNA865380
